Only one fork
Fixing one event that splits the worlds keeps the story sharp. A moment you can date is best: the college choice at nineteen, the confession that night, the city you never left. Show the later differences as ripples from that single fork.
Two-character sheet
| Item | Me here | Me there |
|---|---|---|
| What I chose at the fork | ||
| Work now | ||
| Where I live | ||
| Who is beside me | ||
| Habits both still have | same | same |
| What each envies in the other |
The "habits both still have" row is the key. Small shared details like the morning coffee, a turn of phrase or staring out the window at night make readers feel the two are one person.
